Output 242 V / 6 A
IC revisionB

Description

This single-stage LLC converter reference design illustrates how to convert AC input voltage (100-120 Vac and 200-240 Vac) to isolated ±42-V DC output with the UCC256302 resonant controller. The design has a regulated ±42-V output that can handle up to 6 A of continuous output current and 12 A of peak current for 100 ms.

Features

  • 100–120-Vac or 200–240-Vac input range operation without front-end PFC
  • Provides ±42-V at 6-A continuous/12-A peak output current for audio amplifier
  • More than 95% peak efficiency and less than 500-mW standby power consumption at 230-Vac

Typical applications

  • Audio amplifier
